Feature Request: Support rotation of 1 or more screens

[Rodney Beede]

I have a 2 external monitor setup. One monitor is the normal horizontal (1920x1200) while the other is vertical (1200x1920).

I couldn't figure out if disper had a way to rotate one of the screens. I think TwinView is being enabled by default which doesn't support screen rotation especially of only 1monitor and not the other.

disper -i < disperDocked

file disperDocked:
backend: nvidia
#DFP-0 is the notebook LCD. NVIDIA Quadro 2000M (and just regular 2000) are limited to 2 displays at once
associated displays: DFP-1, CRT-0
metamode: DFP-1: 1920x1200 @1920x1200 +0+0, CRT-0: 1920x1200 @1920x1200 +1920+0
xinerama info order: DFP-1, CRT-0

An xorg.conf that works (without using disper and requiring a reboot):

[I manually added the Option "Rotate" "left" after using nvidia-settings]
